I would recommend to add a small patch that extends iopoll.h by ioreadXX() variants.
Or as alternative just define it here at the top of the file (or in one of the
header if it's used more than in one module) so we may move it to the iopoll.h
in the future:
#define ioread32_poll_timeout_atomic(addr, val, cond, delay_us, timeout_us) \
readx_poll_timeout_atomic(ioread32, addr, val, cond, delay_us, timeout_us)
